The toast sandwich "recipe" apparently dates back to the infamous Victorian-era Mrs Beeton cookbook, but it's seen a revival of interest this week in the UK after the Royal Society of Chemistry (RSC) described it as the UK's "cheapest meal".

The RSC estimates that a single toast sandwich costs around 7.5 pence (around 12 cents). In Australia, it's marginally more. (I noted myself earlier this year that bargain-priced groceries are even cheaper in the UK than they are here.)

If you picked up a $1 loaf and it has about 20 slices, the bread will cost 15 cents. You could allow a couple of cents or so for el-cheapo margarine, so it does come in as slightly cheaper than a packet of 2-minute noodles (around 23 cents if bought in bulk). I don't think I'd make it a regular part of my menu, but I am strangely tempted to try it.

OK, LifeHacker. I took the bait, and just made myself a fresh and tasty toast sandwich.

Verdict: There's a little bit of food psychology going on here. The warmth and crunchiness tricks your brain into thinking it's getting a yummy treat, but then the tastebuds kick in and sharply remind you that it's nothing but bread-on-bread action. Something akin to pleasurably viewing the fashion channel when it unexpectedly crosses to male haute couture at a critical moment

Henceforth, I shall rename this culinary delight Mouthful o' Sadness, and may we never speak of this insanity again.

If you want true cheapassness, try a piebuddy. 2 pieces of bread, with half a home-brand meat pie between them. So one pie (which in home brand flavour comes in at like 40c) plus 4 pieces of bread, and you've got a pretty filling meal for around 50cents.

When times were tough back in the day (like 5 years ago for me lol). I'd only eat wholemeal toast with a small amount of butter. I mean like every day. 2 slices here, 4 slices there etc. I was dead broke (because I was immature with cards and bills)... Funny thing is, with all the bread (carbs) i'd eat. I LOST weight lol... So win win i guess...haha

Got home hungry @ 11pm, and was too tired to actually make something substatial - so tried this (albeit, with one slice of bread cut into 3 - I'm poor and didn't want to waste 3 pieces of bread if I hated it).

Either I was so hungry that I'd eat anything, or it was actually good.
I used thick wholemeal bread, margarine and salt (I don't like pepper).
Kind of reminded me of a hot chip sandwich - which I love. You get the crunch and salt like you would if you had chips as your filling.

Granted I only had the equivalent of 1/3 of this meal, so if you were to make the full option, it may get dry toward the end.

Did not think much of this but today when I was making a Vegemite Sandwich with the last of the bread I had a slice of bread left over so I toasted it buttered it on both sides and put it in the Vegemite Sandwich, it added a nice warm crunch. So a straight Toast Sandwich - I don't think so, but as a cheep addition to jazz up a regular sandwich - its a winner.
